As well known, the progress of the photodegradation of LDPE proceeds through the formation of oxygencontaining groups, such as carbonyl groups (namely, carboxylic acid and ketones at 1713 [cm.sup.-1], esters at 1730 [cm.sup.-1], and lactones at 1780 [cm.sup.-1]) and hydroxyl groups (free or linked OH groups) and the formation of vinyl unsaturation (vinyl groups at 909 [cm.sup.-1]) [23, 26]; differently, the progress of the photodegradation of PA, in the presence of humidity, proceeds through random chain scission reactions and the formation of carbonyl and/or carboxyl groups (shoulder at 1711[cm.sup.-1]) [21].

The present project seeks to know the application of discarded plastics LDPE, PET and HDPE as biofilm support in aerobic biological reactors, as these materials are the most common plastic wastes found in the south of Ecuador, furthermore, to apply the LDPE, it was thermally modified to increase the density and enhance the surface roughness.
PPIA told the Tariff Commission that the imposition of zero duty from 10 percent on LDPE, the raw material used in the production of plastic packaging materials and which is not locally produced, will reduce their cost and make them stay competitive.
"These two new LDPE grades for the cross-link foaming process are the latest examples from Sabic of such innovative solutions developed together with our customers and value chain partners," concluded Frank de Vries.
